69° on Nov. 15, 1999, the hottest reading for this week of the year since 1897. Next is 68° in 1980.
Woodruff’s center stands about 6,340 ft above sea level. Within three miles the land runs from 6,280 ft to 6,700 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Red Spur Mountain, about 8,860 ft, 15 miles west-northwest.
Under the town center the state geologic map shows Alluvium and colluvium (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, mixed-clastic. Age: Late Cretaceous to Early Eocene, 48 to 100 million years old. About 11 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Arenite. Age: Middle Pennsylvanian to Permian, 290 to 315 million years old. About 3 mi of the line.
Limestone, siltstone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Limestone. Age: Early Mississippian, 347 to 359 million years old. About 0.9 mi of the line.
Coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Woodruff reaches Great Salt Lake by way of Genes Creek and the Bear River: about 400 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Woodruff; river miles along the main stem, rounded.
Woodruff has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 2° in January. A normal year brings about 50 inches of snow; with the rain, that comes to about 10 inches of water.
On November 14 Woodruff normally reaches 44° and falls to 14°. The record high is 64°, in 2025; the record low −20°, in 1925. The most rain on this date, 0.44 in, fell in 1958.
